Alan Donovan e2921e188a go.tools/importer: make loading/parsing concurrent.
1. ParseFiles (in util.go) parses each file in its own goroutine.

2. (*Importer).LoadPackage asynchronously prefetches the
   import graph by scanning the imports of each loaded package
   and calling LoadPackage on each one.

   LoadPackage is now thread-safe and idempotent: it uses a
   condition variable per package; the first goroutine to
   request a package becomes responsible for loading it and
   broadcasts to the others (waiting) when it becomes ready.

ssadump runs 34% faster when loading the oracle.

Also, refactorings:
- delete SourceLoader mechanism; just expose go/build.Context directly.
- CreateSourcePackage now also returns an error directly,
  rather than via PackageInfo.Err, since every client wants that.
